PVD/VM Coatings

Physical Vapor Deposition (PVD) or Vacuum Metallization (VM) adds a measure of Bling! to more ordinary looking parts. An injection molded wheel cover becomes a bright chrome piece of trim.  An inexpensive plastic case can look like it is made of brushed stainless steel.

But while these metallized layers are pleasing to look at - they are not very durable. That is because the PVD/VM process deposits a metal layer that is only Angstroms thick. So VM coatings alone do not have the surface properties required for most products.

Another common problem with VM parts is that the very smooth metal appearance is difficult to achieve over many molded parts which have surface imperfections and irregularities. A primer can help fill voids and provide a smooth surface for metallization.

If you are considering PVD/VM for your cosmetic parts, Kalcor has developed line of products to help achieve the look you are seeking:

• PVD/VM Primers to give molded plastics the necessary smoothness needed for metallizing
   
• Tinted basecoats compatible with various target metals to provide even more design freedom
   
• Robust top clear and tinted coats that adhere to PVD/VM surfaces and provide toughness
